Symptoms

On : 2.4.0.1.0 version, NMS Infrastructure

Running nms-control-zones ( or ces_control_zones.ces in releases prior to 2.5 ), this appeared in the log file:

(13:15): Checking discrepances between feeder_ncg and control_zones tables...
(13:15): Checking for orphaned control_zones..
ERROR - No children for class=4805 name=[(m)<feeder name>]
(13:15): Checking for orphaned control_zone_structures..
(13:15): Validation completed, exiting.
(13:15): Error: 1 config issues - please resolve - tables unchanged
(13:15): Info: exiting.
 
The [project]_control_zones.dat file did not have any entries for the feeder .
There was one active entry in CONTROL_ZONES for the named zone.

They ran these queries:

select * from control_zones;
select * from control_zone_structures;
select * from feeders;
select * from feeder_ncg;
select * from valid_ncgs;

select count(1) from network_components where ncg=&NCG_ID and death is null;
select count(1) from network_nodes where ncg=&NCG_ID and death is null;

And they confirmed that there were no active entries for the NCG in any of these tables: CONTROL_ZONE_STRUCTURES, NETWORK_COMPONENTS, NETWORK_NODES, OBJECT_INSTANCES, FEEDER, FEEDER_NCG or the VALID_NCG view.

Changes

Several feeders (and their corresponding control zones) were retired from the model.
